A study reported in the American Journal of Clinical Nutrition has found that the highest levels of omega 3 fatty acids found in red blood cells were strongly associated with corresponding increased life expectancy.
This was a longitudinal study over 11 years. People in the top 5th of the erythrocyte fatty acid group had a life expectancy of 5 years more than the people in the bottom 5th.
This is actually as strong an association with mortality and cardiovascular events as traditional factors such as blood pressure, serum lipids and diabetes.
